SIDEWALK-VENTILA TOR.

Specification of Letters Patent.

Patented Aug. 18, 1908.

Application filed October 8, 1907. Serial No. 396,424.

T 0 all whom it may concern:

Be it known that I, MARTIN CARROLL, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements inSidewalk-Ventilators, of which the following is a specification.

My invention relates to improvements in sidewalk ventilators.

The object of my invention is to provide an improved form of sidewalkventilator by which air and light may be readily admitted to the areabelow the sidewalk, novel means being provided by which, in stormyweather,

water and dirt may be prevented from entering the area through theventilator.

The novel features of my invention are hereinafter fully described andclaimed.

In the accompanying drawings illustrative of my invention-Figure 1 is aperspective view of my improved sidewalk ventilator as it is mounted ina concrete pavement, a portion of the top of the ventilator being brokenaway. Fig. 2 is a vertical sectional View, taken transversely across theventilator on the dotted line ab of Fig. 3. Fig. 3 is a cross sectiontaken on the dotted line ef of Fig. 2. Fig. 4 is a vertical sectionalview taken on the dotted line cd of Fig. 2. Fig. 5 is a view similar toFig. 2 the closure for the ventilating openings being shown in theclosed position in Fig. 2 and in the open position in Fig. 5.

Similar characters of reference denote similar parts.

The ventilator comprises preferably, a rectangular, horizontal hollowbody provided with a closed top 1 and vertical side walls 2. The top 1may be provided with translucent glass plates 3 embedded horizontally incement or concrete 4 which is supported by horizontal rods 5, which inturn rest at their ends upon horizontal flanges 6 provided in the top 1and extending along the sides of a rectangular opening 7 provided in thetop of the body 1. One or all of the side walls 2 are provided each withone or more transverse .incline downwardly and outwardly in the sameplane, so that water entering the openings S will run outwardly insteadof into the area under the sidewalk. Extending transversely across theopenings 8 upon the upper sides and adjacent the inner edges of theflanges 9 are provided flanges 11, each of which extends vertically in acorresponding longitudinal groove, provided in the lower side of aclosure 12 secured by hinges 13 to the inner side of the flange 9. Theclosure 12 is preferably in the form of a quarter round, the flat sideof which, provided with the groove fitting the flange 11, rests upon theupper side of the flange 9 when the closure 12 is in the closed positionshown in solid lines in Figs. 3 and 4.

posed at the inner sides of curved screens 14 extending one across theinner end of each ventilating opening 8. One closure 12 is shown in thedrawings. If other closures are employed they are constructed in thesame manner as the one illustrated.

Each closure on the side which is the inner side when the closure is inthe closed position, is provided with a hand hold, such as a hook 15, bywhich the closure may be swung to and from the closed position. Theclosure 12, when in the closed position, serves as a support whichprevents the screen 14 from being inwardly bent by sticks or otherobjects which may be accidentally or otherwise inserted through theopenings 8. The closure 12 is preferably provided on its inner side witha depression 16 in which the head of the hook 15 is located. Suchdisposal of the hook 15 lessens its liability to injury.

The underside of the body of the ventilator is preferably provided withfour downwardly extending flanges 17, joined at their respective ends toform a rectangle and which, when embedded in the concrete 18, formingthe pavement, prevent lateral movement of the ventilator. When theventilator is set in the concrete 18, the upper sides of the flanges 10are preferably flush with the upper side of the concrete pavement 18.

Various modifications of my invention within the scope of the appendedclaims may be made without departing from its spirit.

Having thus described my invention what I claim and desire to secure byLetters Patent is 1. A sidewalk ventilator having a horizontal, hollowbody closed at the top and having a ventilating opening in one sidewall, a horizontal flange extending outwardly from said wall the upperside of said flange and the lower side of said opening incliningoutwardly and downwardly in the same plane,

and a hinged closure for the inner end of said opening.

2. A sidewalk ventilator having a horizontal, hollow body closed at thetop and having a ventilating opening in one side wall, a screen acrossthe inner end of said opening, a hinged closure for the inner end ofsaid opening, and a horizontal flange extending outwardly from said wallthe upper side of said thereon when in the closed position.

4. A sidewalk ventilator having a horizontal, hollow body closed at thetop and having a ventilating opening in one side wall, a horizontalflange extendin inwardly from said wall, the upper side 0? said flangeand the lower side of said- 0 ening being in the same plane, and avertica flange on the upper side of said inwardly extending flange andextending across said opening.

5. A sidewalk ventilator having a horizontal, hollow body closed at thetop and having a ventilating opening in one side wall, a horizontalflange extending inwardly from said wall, the up er side of said flangeand the lower side 0' said opening inclining downward and outward in thesame plane, and a vertical flange extending across said opening upon theupper side of said inwardly extending flange.

6. A sidewalk ventilator having a horizontal, hollow body closed at thetop and having a ventilating opening in one side wall, a horizontalflange extending inwardly from said wall, the upper side of said flangeand the lower side or said opening inclining in the same planedownwardly and outwardly, a vertical flange extending across saidopening upon the upper side of said inwardly extenda screen across saidopening.

ing flange, and a closure for said opening hinged to said inwardlyextending flange.

7. A sidewalk ventilator having a horizontal, hollow body closed at thetop and having a ventilating opening in one side wall, a hori zontalflange extending inwardly from said wall, the upper side of said flangeand the lower side of said opening being in the same plane, averticalflange extending across said opening upon the upper side of saidinwardly extending flange, a closure for said opening hinged to saidinwardly extending flange, and

8. A sidewalk ventilator having a horizontal, hollow body closed at thetop and having a ventilating opening in one side wall, a horizontalflange extending inwardly from said wall, a horizontal. flange extendingoutwardly from said wall the up er sides of said flanges and the lowerside of said opening inclining downwardly and outwardly in the sameplane, and a closure for the inner end of said opening hinged to saidinwardly extending flange which supports said closure in the closedposition.

9. A sidewalk ventilator having a horizontal,.hollow body closed at thetop and having a ventilating opening in one side wall, a horiwall, ahorizontal flange extending outwardly from said wall, the upper sides ofsaid flanges and the lower side of said opening inclining downwardly andoutwardly in the same plane, a vertical flange extending across saidopening upon the upper side of the inwardly extending flange, and aclosure for the inner end of said opening hin ed to said inwardlyextending flange, said c osure MARTIN CARROLL.
